The findings reveal how the demands of performance dramatically change depending on race distance, highlighting the importance of physiology, training consistency, psychology and fueling strategies.Next, Brodie unpacks a controversial new systematic review and meta-analysis on shockwave therapy for Achilles tendinopathy. Does shockwave actually improve outcomes, or has the treatment become overhyped within sports medicine? The findings may surprise clinicians and runners alike.Finally, a new plantar fasciitis paper explores whether arch supports genuinely help reduce pain and — more importantly — why. Using imaging, biomechanics and computational modeling, the researchers attempted to uncover the mechanical effects of orthotics and how they may redistribute stress through the foot.Papers discussed in this episode1. Performance predictors in recreational runnersA systematic review examining the factors associated with performance in non-elite runners across distances ranging from 5K to ultramarathons.Topics discussed: VO₂ max and running economy  Strength training and plyometrics  Weekly mileage and consistency  Emotional intelligence and pacing  Fueling strategies in ultramarathons  Environmental impacts on performance 2. Shockwave therapy for Achilles tendinopathyA systematic review and meta-analysis investigating whether shockwave therapy improves outcomes for midportion and insertional Achilles tendinopathy.Topics discussed: Radial vs focused shockwave  Placebo effects and sham treatment  Exercise vs shockwave outcomes  Why exercise-based rehab still remains the gold standard  Whether shockwave is worth the cost 3. Arch supports and plantar fasciitisA prospective study exploring the effects of arch-support insoles on pain, foot alignment and heel stress distribution in plantar fasciitis patients.Topics discussed: Orthotics and pain reduction  Foot alignment changes on imaging  Heel pressure redistribution  Finite element biomechanical modeling  Why orthotics may help symptoms without restoring tissue capacity Key takeaways The predictors of running performance depend heavily on race distance.  Strength training continues to show benefits for running economy and shorter-distance performance.  Marathon success is strongly linked to consistency and uninterrupted training.  Ultramarathons rely increasingly on pacing, fueling and race management rather than pure physiology.  Current evidence for shockwave therapy in Achilles tendinopathy remains inconsistent and underwhelming.  Exercise-based rehab continues to have the strongest evidence for tendon recovery.  Arch supports may reduce plantar fascia stress and improve symptoms short-term, but should not replace progressive loading strategies.
